Push one or more elements onto the end of array (PHP 4, PHP 5)
int array_push ( array &array, mixed var [, mixed ...] )

array_push() treats array as a stack, and pushes the passed variables onto the end of array. The length of array increases by the number of variables pushed. Has the same effect as:

[] = $var;

repeated for each var.

Returns the new number of elements in the array.

Example 271. array_push() example

= array("orange", "banana");
array_push($stack, "apple", "raspberry");

The above example will output:

0] => orange
[1] => banana
[2] => apple
[3] => raspberry
) ?>


If you use array_push() to add one element to the array it's better to use $array[] = because in that way there is no overhead of calling a function.


array_push() will raise a warning if the first argument is not an array. This differs from the $var[] behaviour where a new array is created.
